The 4 questions - these questions are traditionally asked by the youngest child at the table. If he/she is able, they are chanted in Hebrew.
Why is this night different from all other nights?
On all other nights we eat leavened products and matzah, and on this night only matzah.
On all other nights we eat all vegetables, and on this night only bitter herbs.
On all other nights, we don’t dip our food even once, and on this night we dip twice.
On all other nights we eat sitting or reclining, and on this night we only recline.
The 4 Children (or 4 sons) - in the middle of the Seder, we read a passage about the 4 types of children:
The wise child
The wicked child
The simple child
The child unable to inquire
The holiday and the story must be explained to each type of child according to their ability. These designations apply to more of life than just explaining Passover. The wise child asks insightful questions about the holiday, the wicked child scorns the holiday, and the simple child asks "what is this?." The child unable to inquire could be a baby who can't talk yet. My personal thought is that most children are more than one, perhaps all, of these over the many years of childhood.
4 Glasses of wine
Traditionally, during the Seder, we say the blessing over the fruit of the vine 4 times and drink 4 glasses of wine. Some people drink tiny glasses while others get drunk. Some people drink grape juice. Traditionally, we drink the wine from ornate silver cups called Kiddush cups. In some families only the leader and/or Elijah have ornate kiddish cups. Some families have tiny little silver cups so each person has a silver cup. Other families use wine glasses or regular cups.
For this challenge, I want you to make a holiday card with 4 holiday symbols. I seem to have used this idea many times for Passover, here are some cards from my gallery with 4 symbols:



You may create a card for any holiday religious or secular as long as it contains 4 symbols associated with that holiday. It can be 4 different symbols or the same symbol repeated.
Rules:
1. Create a holiday card that contains 4 symbols of the holiday
2. You may combine with one other challenge that allows combining plus any monthly, team, or cumulative challenges (the normal rules). You may not combine with another Passover challenge.
3. One entry per person
4. Due April 30th at midnight.
5. One entry randomly chosen will win a $5 ACOT gift card from me.
